HENRY F. BENDER, OF GUNNISON, CGLORADO.

SASH-FASTENER.

Application filed July 13, 1915.

To @ZZ whom t may concern.'

Be it known that I, HENRY F. BnNDnr., a. citizen of the United States,residing at Gunnison, in the county of Gunnison, State of Colorado, haveinvented certain new and useful Improvements in Sash-Fasteners; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The present invention is directed to iinproveniente in sash fasteners,and has for its object to provide a device of this character capable ofbeing easily and quickly attached to the window sash.

A further object of the invention is to provide a sash fastener soconstructed that the locking action thereof is positive.

A still further object of the invention is to provide a device of thistype which is eX- tremely simple in construction, and one which iscapable of locking the sash in closed, or partly closed position.

lVith these and other objects in view, this invention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed and illustratedin the accompanying drawing, in which Figure 1 is a fragmentary sideelevation of a window frame and sash, showing the fastener operativelyconnected thereto. Fig. 2 is a sectional view on line 2 2 of Fig. 1. Fig. 3 is a front elevation of the device, the cover plate broken away.Fig. 4 is a detail perspective view of a portion of the device.

Referring to the drawing 1 designates the side stile of the window sash,and 2 the adjacent side of the window frame, which is provided with aplurality of horizontally disposed sockets 3, the purpose of which willappear later. The stile 1 is provided with a transverse groove il, whichis adapted to receive the elongated seat 5, which is semi-circular incross section and has its side edges terminating in horizontal flanges6, which are attached to the stile l by spurs 7, said spurs being formedon the flanges by puncturing the saine with a suitable tool. The seat 5is provided at one end with a semi-annular flange 8, which is adapted toengage one end of the coil spring 9, said coil spring encircling thevbolt 10 between Specification of Letters Patent.

the shoulders 11 and 12. The other end of the spring 9 engages theshoulder 11. A plate 13 is provided and is secured to the stile l in anysuitable manner, and serves to cover the seat 5, thereby preventing thebolt 10 from accidentally disengaging said groove. The plate is providedwith a fiange 14 which engages one side of the stile 1, and is providedwith a perforation 15 for slidably receiving the bolt 10. The outer endof the bolt 10 is provided with an actuating knob 16.

From the foregoing description it will be seen that the spring 9normally holds the bolt 10 engaged in one of the sockets 3 formed in thewindow frame, thus positively locking the sash. When it is desired tounlock the sash it is only necessary to grasp the knob 16 and withdrawthe bolt 10 from engagement with the socket 3, which action compressesthe spring 9, so that when it is desired to again lock the sash thespring 9 will expand and force the bolt into engagement with the desiredsocket.

What is claimed is A window fastener, in combination with the side stileof the sash, said stile having a transverse groove formed therein, aseat engaged in said groove and having flanges carried by its side edgesfor engagement with the stile, one end of said seat being provided witha semi-annular flange, a plate attached to the stile for closing thegroove, said plate having a Harige for engaging the side of the stile,and having a perforation formed therein, a bolt slidable in the seat andperforation, said bolt having annular shoulders disposed in spacedrelation, a coil spring encircling that portion of the bolt between theshoulders, and having one end engaged with the semi-annular flange andthe other end engaged with one of the shoulders, the other shoulderbeing adapted to engage the outer surface of the semi-annular flangesaid spring serving to hold the bolt in yielding engagement with theside of the window frame.

In testimony whereof, I affix my signature, in the presence of twowitnesses.
